For the second time in as many months, Six Flags Magic Mountain has pushed back the opening of the rocking and spinning Green Lantern roller coaster. It is now scheduled to make its debut July 1 after the Valencia amusement park postponed planned premieres in May and June.

We can probably cut Magic Mountain some slack, though. The park updated Superman: Escape from Krypton in March and added the Road Runner Express kiddie coaster over Memorial Day weekend. Green Lantern: First Flight, the park's 18th coaster, will make Magic Mountain the undisputed "Roller Coaster Capital of the World," breaking a tie for the most coasters with Cedar Point in Ohio.

Park officials said the delay in Green Lantern's debut was not caused by mechanical issues but rather last-minute design changes to the coaster's loading station.

Crews have completed construction on the vertical, emerald-green track and continue to assemble the five throwing-star-themed coaster cars, with on-track testing expected to begin soon. A 10-foot-tall lantern icon near the ride's entrance will glow green at night.

The Green Lantern's vertical zigzag track sits on a compact footprint near the Batman and Riddler’s Revenge coasters. The new-concept, fourth-dimension coaster, similar in style to X2 but much tamer, will reach a top speed of 37 mph over 825 feet of serpentine track during the two-minute ride.

Upon boarding a train that straddles the track, riders face in two directions, forward and backward. A chain lift carries each car up an inverted curved section to a height of 107 feet. From there, the suspended trains rock back and forth on the straightaways and rotate head over heels as the cars plunge over freefall drops.

The Intamin ZacSpin coaster is making its U.S. debut at Magic Mountain. The Grona Lund theme park in Stockholm added an identical ZacSpin called "Insane" last year, with smaller versions of the ride also operating in Spain and Finland.

The vertical Green Lantern: First Flight spinning roller coaster at Six Flags Magic Mountain in Valencia, set to open on July 1, features suspended trains that rock back and forth on the straightaways and rotate head over heels as cars plunge over free-fall drops.

I used to think the ride on the Superman shuttle coaster essentially ended when the car reached the climatic 415-foot-high peak. But now that Six Flags Magic Mountain has flipped the trains around to run backward, the fun is just getting started when you reach the top.

There's a lot more than pixie dust swirling through the air at the Disneyland resort as construction crews, excavators and towering cranes work on several new theme-park rides set to debut this summer and beyond.
